Even though there are already a number of heroes and villains populating its cast, might we be seeing another giant-sized villain appear in Batman v Superman: Dawn of Justice? Bleeding Cool has gotten hold of a rumor from a source who claims to have seen designs for a version of the killing machine Doomsday for the highly-anticipated film. Even though the character was teased in the bonus features on the Man of Steel Blu-ray, treat this one as a rumor for now and check back for any potential confirmation.

Created by Dan Jurgens for the 1992 event series “The Death of Superman,” Doomsday is a genetically engineered monster that has the distinction of being the character that killed Superman. He has appeared a number of other times in the comics despite perishing himself, and even took on the role of the primary antagonist for a season of “Smallville.”

Starring Henry Cavill, Ben Affleck, Gal Gadot, Amy Adams, Laurence Fishburne, Diane Lane, Jesse Eisenberg, Jeremy Irons, Holly Hunter and Scoot McNairy, the DC Comics film brings together the Man of Steel and the Dark Knight — for the first time on the big screen.
